Definitions
- the present invention relates to systems for pressure isolation of one or more tools adapted for use in a wellbore.
- Hydrocarbons such as oil and gas are recovered from a subterranean formation using a wellbore drilled into the formation.
- a number of tools are used throughout the process of drilling and completing the wellbore and also during the production life of the well. Many of these tools are energized using pressurized fluid that is self-contained in the tool, pumped downhole from the surface, or fluid that is produced from the well itself. These tools, which are sometimes referred to as hydraulically actuated tools, can be put to a number of uses.
- One use for hydraulically actuated tools is to set a liner hanger.
- the liner hanger is used to hang or anchor a liner off of a string of other casing string.
- liner hangers are known in the art, which includes hydraulic liner hangers.
- fluid is supplied under pressure into an annular space between a mandrel and a surrounding cylinder. The hydrostatic pressure of the fluid between the cylinder and the mandrel creates a force on the inner surface area of the cylinder that causes the cylinder to slide longitudinally.
- Hydraulically actuated liner hangers are illustrative of wellbore tools that utilize an applied fluid pressure for operation.
- an isolation device protection device includes a sealing member positioned proximate to the port that moves into a sealing relationship with the port after the wellbore tool has been set.
- An actuating member positioned next to the sealing member translates or otherwise displaces the sealing member into scaling engagement with the port.
- actuating member includes a biasing element such as a spring and is retained in a pre- activated position by a retaining element.
- the retaining element can include a shoulder or stop formed within the wellbore tool.
- the present invention can be used to protect portions of hydraulically actuated wellbore tools such as liner hangers.
- Liner hangers typically include a cylinder disposed around a mandrel. The cylinder slides along the mandrel when an applied pressure of a sufficient magnitude is generated in a pressure chamber in the liner hanger. This pressure chamber communicates with the tool flow bore or wellbore via a port formed in the mandrel.
- the sealing member can seal off the port after the applied wellbore pressure sets the wellbore tool.
- components such as seals or thin walled cylinders are isolated from fluid pressure in the wellbore.
- the sealing member can include sealing elements to ensure that fluid does not leak out of the pressure chamber as the applied pressure is setting the hydraulically actuated tool. If, after setting s the fluid in the pressure chamber prevents the sealing member from seating properly over the port, then the sealing member includes a flow element such as a valve that selectively bleeds fluid from the pressure chamber after the wellbore tool has been set.
- the isolation device can be configured to operate liner hangers as well as other tools used in the wellbore.
- the pressurized fluid can be water, synthetic material, hydraulic oil, or formation fluids.

- the present invention relates to devices and methods for pressure isolation of hydtaulically actuated wellbore tools.
- the present invention is susceptible to embodiments of different forms. There are shown in the drawings, and herein will be described in detail, specifics embodiments of the present invention with the understanding that the present disclosure is to be considered an exemplification of the principles of -the invention, and is not intended to limit the invention to that illustrated and described herein. Indeed, as will become apparent, the teachings of the present invention can be utilized for a variety of well tools and in all phases of well construction and production. Accordingly, the embodiments discussed below are merely illustrative of the applications of the present invention.
- a pressure isolation device 100 made in accordance with the present invention for pressure isolating one or more sections of a tool 10 conveyed via a work string 12 into a wellbore.
- the isolation, device 100 can be used in connection with nearly any tool, for simplicity, the isolation device 100 will be discussed in the context of a hydraulically actuated liner hanger having an outet member or cylinder 14 and an inner member or mandrel 16.
- a port 18 formed in the mandrel 16 provides fluid communication between a tool bore 20 and a chamber 22.
- the chamber 22 is hydrauIicaUy sealed by seals or packing 24 and the isolation device 100.
- a pressure increase in the bore 20 causes a corresponding pressure increase in the chamber 22.
- the applied pressure generates a force that urges the cylinder 14 to slide in the direction 24.
- This sliding movement can actuate slips (not shown) in the case of liner hangers or open or close a valve or perform some other desired function.
- the isolation device 100 seals the port 18 to thereby substantially prevent fluid communication between the bore 20 and the chamber 22 and other external sections of the tool 10. As should be appreciated, this isolation can shield external components of the tool 10 from relatively high pressures in the bore 20 that may be generated during activities such as pressure testing.
- the isolation device 100 includes a sealing member 102 positioned in. a space 104 between the cylinder 14 and the mandrel 16.
- the sealing member 102 includes a ring-like body 106 on which are positioned sealing elements 108.
- An actuating element 110 adjacent to the sealing member 102 pushes or slides the sealing member 102 over or around the port 18 once a predetermined pressure condition is reached.
- the actuating element 110 is a biasing member such as a spring that is retained within the space 104 by a retaining member 112.
- the actuating element 110 can use pressurized fluid such as gas, an electric or hydraulic motor, one or more magnetic elements, piezoelectric elements and other devices suited to push or otherwise displace the sealing member 102.
- the sealing elements 108a-c are disposed on both the interior and exterior surfaces of the body 106 to form fluid barriers between the body 106 and the cylinder 14 and between the body 106 and the mandrel 16.
- the interior and exterior sealing elements 108a-c cooperate to allow the chamber 22 to develop a pressure differential sufficient to displace the cylinder 14.
- the interior seals 108 a,b straddle and seal off the port 18. These seals, which do not need to be a "zero leakage" seals, enable a substantial pressure differential thereacross. It should be understood that any number of different sealing arrangements can be utilized.
- a sealing element (not shown) can be positioned in the retaining member 112, which could eliminate the need for a sealing element on the exterior surface.
- a biased detent element such as a ball may be used to plug the port 18, which could eliminate the need for a sealing element on the interior surface.
- the tolerances between, the sealing member and the mandrel and the cylinder can be selected to reduce fluid leakage to a level where no seal elements would be needed.
- the sealing member 102 can include one or more flow control elements 112.
- the flow control element H2 permits fluid to flow out of the chamber 22 under one or more preset conditions.
- the flow control element 112 includes a valve 114 that selectively blocks fluid communication through a conduit 116 traversing the sealing member 102.
- the valve 114 includes a piston member 118 that is urged to an open position by a biasing member 118. A suitably high hydraulic pressure in the chamber 22 urges the piston member 118 into a closed position.
- a shoulder 122 is formed on the cylinder 14 that protrudes into the space 104 to provide a seating surface for piston member 118 of the valve 114.
- the biasing force generated by the actuating member 110 overcomes the biasing force of the biasing member 118, which allows the piston member 1.18 to move, ⁇ n another embodiment, the flow control element 112 can include a rupture disk (not shown) that fractures or disintegrates at a predetermined pressure. In still other embodiments, the flow control element 112 can include plugs or other elements that melt or disintegrate upon exposure to heat, pressure, a chemical, etc.
- the isolation device 100 is shown in a pre-activated position wherein the port 18 is unblocked and fluid flows freely between the bore 20 and the chamber 22.
- the pressure in the chamber 22 can vary as the tool 10 is tripped into the well; e.g., it could be at, below or above a hydrostatic pressure. These pressure variations do not affect the isolation device 100.
- the shoulder 122 prevents sliding or translation of the sealing element 102 in the direction 24. Additionally, pressure variations will not affect the valve 118, which is held in a closed position by the actuating element 112 pressing the valve 118 against the shoulder 122.
- the tool 10 is shown in a condition where the pressure in the chamber 22 has reached a preset value and has caused the cylinder 14 to slide axially relative to the mandrel 16.
- This preset pressure value can be selected to fracture a device such as a shear screw 26 (Fig. 1) that initially fixes the cylinder 14 to the mandrel 16.
- the preset pressure value or applied pressure in the chamber 22 is selected maintain the isolation device 100 in a pre-activated or dormant condition even after the shoulder 122 slides away from the sealing member 102.
- the applied pressure can overcome the bias of the actuating member 110 (Fig.
- valve 118 is open, the chamber 22 is no longer hydraulically sealed; i.e., fluid can escape the chamber 22 via the conduit 116, Thus, advantageously, even after the sealing device 102 seals off the port 18, fluid can be bled from the chamber 22 via the conduit 122.
- the sealing device 102 is shown surrounding and sealing off the port 18.
- the body 106 and the seals 108a,b form a fluid barrier that prevents fluid communication between the bore 20 and the exterior portions of the tool ,1,0.
- the tool 10 is isolated from pressure variations, e.g., pressure increases, in the bore 20.
- pressure isolation can simplify the design of the tool 10 and also increase the in-service reliability and robustness of the tool 10.
- the seals or packing 24 do not necessarily have to be configured to withstand pressures substantially beyond the pressure needed to operate the tool 10.
- the cylinder 14, which can have a relatively thin wall also does not necessarily need specialized materials to withstand such pressures.
- the isolation tool 100 can include a stop member 140 positioned on the mandrel 16 to axially position the sealing device 102 over the port 18.
- the stop member 140 can be a snap ring or other protruding member located such that when the sealing device 102 abuts the stop member 140, the port 18 will be axially straddled by the seals 108a,b.
- the stop member 140 can be configured to engage and close the valve 118 in much the same manner as the shoulder 122.
- FIG. 5 there is shown a well construction facility 200 positioned over subterranean formation 202. While the facility 200 is shown as land- based, it can also be located offshore.
- the facility 200 can include known equipment and structures such as a derrick 204 at the earth's surface 206, a casing 208, and mud pumps 210.
- a work string 21.2 suspended within a well bore 214 is used to convey tooling and equipment into the wellbore 214.
- the work string 242 can include jointed tubular s, drill pipe, coiled tubing, production tubing, line ⁇ s » casing and can include telemetry lines or other signal/power transmission mediums that establish one-way or two-way data communication and power transfer from the surface to a tool connected to an end of the work string 212.
- a suitable telemetry system (not shown) can be known types as mud pulse, electrical signals, acoustic, or other suitable systems.
- the tooling and equipment conveyed into the wellbore can include, but are not limited to, fishing tools, expansion tools, bottomhole assemblies, tractors, thrusters, steering units, drilling motors, downhoje pumps, completion equipment, perforating guns, tools for fracturing the formation, tools for washing the wellbore, screens and other production equipment.
- the work string 212 is shown as conveying a liner hanger assembly 216 into the wellbore 214.
- the liner hanger assembly 216 includes a liner hanger 218 and an isolation device 100. Once the liner hanger assembly 216 is positioned that a desired depth, the liner hanger 218 can be actuated in a convention manner.
- a plug or ball can be "dropped" into a tubing bore to isolate fluid communication in the area of the desired depth.
- the mud pump 210 is operated to increase the applied pressure of the drilling fluid in the drill string 212.
- tbe cylinder 14 slides longitudinally in a manner previously described to engage the slips or other tool.
- the pressure in the work string 212 drops.
- the isolation device 100 is activated in a manner previously described and blocks off fluid communication between the interior and exterior of the work string 212.
- the work string 212 can be pressured up to pressure test the liner hanger assembly 216.
- the integrity of the hanger assembly 216 e.g., hydraulic isolation
- the integrity of the hanger assembly 216 can be tested with without exposing the exterior elements of the liner hanger 218 to the elevated test pressures.
- the positive closure of the port 18 by the isolation device 100 increases the overall reliability for the service life of the liner hanger 218,
- fluids such as water, acids, fracturing fluids
- formation fluids such as oil and water can be utilized in some circumstances to energize the isolation device.
- some embodiments of the present invention can be adapted for use in situations where fluid pressure is not used to energize a tool or device.
- some tools may be actuated or energized by vibrations, mud pulse, motion of the tool, frequency, electronic signals, etc.
- first and second and uphole and downhole do not signify any specific priority, importance, or orientation but are merely used in better describe the relative relationships between the items to which they are applied.
- longitudinal generally refers to a direction along the long axis of a weUbore or tool, but as noted above, the isolation device is not limited to motion in any particular direction.
